某高层剪力墙结构消能减震性能分析

Analysis of Energy Dissipation and Shock Absorption Performance of a High-Rise Shear Wall Structure

为研究消能减震技术对剪力墙结构的抗震效果,以某市某高层剪力墙住宅作为工程背景,通过有限元软件ETABS建立原结构和设有黏滞阻尼器的减震结构,并进行时程分析。分析结果表明:无论是在多遇地震下还是罕遇地震下,设有黏滞阻尼器的减震结构在层间剪力和层间位移角方面都明显减小,从而有效减小了地震力对结构的破坏。

In order to study the seismic effect of energy dissipation and shock absorption technology on the shear wall structure,the original structure and the shock absorption structure with viscous damper were established by ETABS finite element software with a high-rise shear-wall residence in a city as the engineering background,and the time history analysis was carried out.The analysis results show that the shear force and displacement Angle between layers of the structure with viscous damper are obviously reduced under both frequent and rare earthquakes,thus effectively reducing the damage of the structure caused by seismic force.
